• Suppose that your prior information about the urn is that a monkey tosses balls into the urn, selecting red balls with 1/4 probability and white balls with 3/4 probability, each ball selected independently. The urn contains 10 balls, and we sample without replacement. (E. T. Jaynes called this the "binomial monkey prior".)

• One urn contains 4 red balls and 6 blue balls. A second urn contains 16 red balls and x blue balls. A single ball is drawn from each urn. The probability that both balls are the same color is 0.44 . Calculate x. (A) 4 (B) 20 (C) 24 (D) 44 (E) 64

An urn has half red and half white marbles. The probability of getting all red or all white in 4 draws is 12.5% and the probability of getting all white or all red in 7 draws is 1.56%. How does one calculate these percentages without knowing the actual numbers of red and white marbles in the urn? An urn contains 10 white marbles, 15 blue marbles, and 20 red marbles. Five marbles are selected, one at a time, with replacement. Find the probability that at least one color will be missing from the 10 selected marbles For example, 6/12 = 6 ÷ 12 = 0.50. If you solve this with a calculator then it is easy to get the answer. However, if you solve this by hand or in your head reducing 6/12 = 1/2 may make the problem easier and you may even recognize that 1/2 = 0.50. Multiplying 0.50 by 100 means that 6/12 = 50%.
